To all whom it may concern:

Be it known that I, JOHN E. HANRAI-IAN, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Single- Tvpe- Casting Attachments; and Ido hereby declare the following to be a full, clear; and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

' This invention relates to type casting attachments for linotypemachines, such as are disclosed in my copending application #732,101filed November 18., 1912, and has for its object to improve the meansfor delivering the metal to the attachment, as will appear more fullybelow.

\Vith these and other objects in view the invention consists in thedetails of construes tion and combinations of parts more fullyhereinafter disclosed andparticularly pointed out in the claims.

Referring to the accompanying drawings forming a part of thisspecification in which like numerals designate like parts in all theviews:Figure 1, is a. plan view of the easting pot and associated partsof a linotype machine with my improvement applied" thereto, and alsoshows in plan a portion of my single type casting attachment made thesubject of my application above; Fig. 2 is a sectional view of thecastingpot and associated parts shown in Fig. 1; Fig. 3 is a sectionalView of the cylinder for delivering molten metal which 1 locate in thelinotype casting pot; and Fig. 4 is a detail, view of the spring means lemploy to control the casting lever of my attachment.

1 indicates a portion of the frame of a linotype machine to which isattached as at 2 the well known operating lever 3, attached to thepiston rod 4', serving to operate the piston 50 in the cylinder 51located in the melting pot 5, and which delivers metal through the spout6 to cast lines of type. l'pivot to said frame as 7 a second lever 8,and connect it to a second piston rod 9*, operating a piston 26, in thecylinder 10, having the inlet 11, the delivery channel 12, anddelivery'spout 13.

The lever 8 is provided with theplate 14, extending over the lever 3, sothat the latter in one of its motions raises the said lever 8, but notin the other. in order to return the raised lever 8, I provide areciprocating rod 16, preferably housed in the casing 17 and surroundedby the spring 18. Said rod is provided with the notch 20, into which Ifits the latch 21, pivoted by the rod 22 to the bracket 23 supportingthe casing 17 and secured to the frame 1, as at 25, as shown. Thepivoting rod 22 carries at its lower end the toe 27 adaptedto turn withsaid rod and latch and to thereupon engage and disengagesaid plate 11.That is to say, when said latch is in position to render said pusher rod16 inactive as by engaging the notch 20, then the toe 27 underlies saidplate'll and holds the lever 8 in its raised and inactive position.lVhen in this position it is evident the linotype lever may rise andfall without affecting the attachment lever 8. It is also desirable tobe able to readily, attach and detach said lever 8 from its piston rod9, and to accomplish this purpose I provide the pin 30 for detachablyconnecting said parts, and also the latch 31 for locking them togetherand unlocking them when desired. The said piston rod 9 is alsopreferably bent or offset as at 3% (Fig. 2) in order to reach theattachment cylinder 10 located to one side in the pot 5 as plainly shownin Fig. 2. -This attachment cylinder is preferably of the constructionillustrated, and may be made from a single piece. Its spout 13, projectsthrough an additional opening 37 in the side of the pot 5, andpreferably located at about 90 degrees from the spout 6.

As the single type casting attachment mechanism. per so designated 'by40' is fully disclosed in my copending application above and forms nopart of the present invention, it will not be described herein furtherthan to say, the molten metal is delivered from the spout 13 to a matrixlocated at l1, and single type are cast, trimmed and deliveredsimultaneously with the casting of lines of type from the spout 6 of thelinotype machine. By this particular improvement, however, the deliveryof the metal to the single type casting attachment 40 is made moreindependent of the operation oi the iinotype machine, for by simplymanipulatthe latch lever 21, the flow of metal to said castingattachment may be readily started or stopped without in any wayinteriering with the operations of the iinotype machine. Farther, theattachment cylinder, T

spout, etc, may be readily removed and cleaned without causing anyinconvenience.

It is obvious that. those skilled in the art may vary the details ofconstruction as well as the arrangement of parts without depart ing fromthe spirit of my invention, and therefore I do not wish to be limited tothe above disclosure, except as may be required by the claims.

What I claim is 2- 1. in a machine of the class described thecombination of means for casting a line of type comprising an operatinglever, a melting pot and a cylinder in said pot; a second leve adaptedto be moved by said operating lever; a second cylinder in said potassociated with said second lever; and means for delivering metal fromsaid second cylinder for casting single type, substantially asdescribed. I

2. In a machine of the class described the combination of means forcasting a line of type comprising an operating lever, a melting pot anda cylinder in said pot; a second lever adapted to be moved by saidoperating lever; a second cylinder in said pot associated with saidsecond lever; and means comprising a piston and spout associated withthe second cylinder for delivering metal from said second cylinder forcasting single type, substantially as described.

lin a machine of the cl: ss described the combination of means forcasting a line of type comprising an operating lever and a melting potassociated with said lever; asecond lever associated with said operatinglever and pot; connections by which said second lever may be raised bysaid operating lever; and means for holding said second lever in itsraised position, substantially as described.

4. In a machine of the class described the combination of a means forcasting a line of type comprising an operating lever and a :melting potassociated with said lever; a

second lever associated with said operating 'lever and pot; connectionsby which said ing'lever; means comprising a spring for normallyreturning said second lever after it has been raised; and means forholding said second lever in its raised position when desired,substantially as described.

6. In a. machine of the class described the combination of means forcasting a line or" type comprising an operating lever and a melting potassociated with said lever; a second lever associated with saidoperating lever and pot; connections by which said second lever may beraised by said operating lever; a cylinder in said pot also associatedwith said second lever; means associated with said cylinder fordelivering metal from said pot; and means for holding said second leverin its raised position, substantially as described.

In testimony whereof I afi'ix my signature, in presence of twowitnesses.
